Spang Power Electronics

What Spang Power Electronics does

Spang Power Electronics is a US-based industrial power electronics manufacturer, founded in 1953 and operating as a division of the privately held Spang & Co. The company designs and produces AC-DC power control and conversion products and systems, with a core portfolio that spans Silicon Controlled Rectifier (SCR) power controllers in both digital (1050 Series, 1050 Nano, 850 Series) and analog variants (450, 650, 750, B-Series, C-Series), custom application transformers, packaged AC and DC power systems, automation control systems, and specialty AC and DC drives. All engineering design is conducted in the United States; manufacturing runs from ISO 9001 certified facilities in Sandy Lake, Pennsylvania and Xiamen, China, with division headquarters in Mentor, Ohio. The product technology supports industrial communication protocols including DeviceNet, Profibus, Ethernet IP, Ethernet Modbus TCP, and Profinet.

Commercially, the company sells through a direct, sales-led motion using specialized Request for Quote forms for SCR power controllers, transformers, and general inquiries, with quote-based pricing driven by detailed customer specifications (voltage, current, power, frequency, phase, temperature rise, mounting). Revenue mechanics are predominantly hardware sales of configured-to-order systems and standard product lines, with multi-year contracts typical for industrial integration projects. Solutions are deeply tailored to specific customer requirements through application engineering collaboration.

The customer base is segmented vertically across eight industrial use cases: glass manufacturing (flat, LCD, container, specialty), hydrogen production via electrolysis, plasma arc (DC plasma and vacuum arc remelting), fibers (fiberglass, carbon fiber, ceramic fiber), coatings (plating, electrocoating, anodizing, thin-film deposition, cleaning), polysilicon and solar manufacturing, industrial heating, and industrial DC rectifiers. Vertical segmentation, proprietary SCR technology (including an industry-first color touchscreen digital controller), and US-led engineering define the value proposition, while global distribution is supported via a multi-language website spanning English, Chinese, German, French, and Japanese.

Core offering

Spang Power Electronics manufactures and sells SCR (Silicon Controlled Rectifier) Power Controllers, Transformers, and packaged Power Systems for industrial applications. The company offers both standard product lines and custom-engineered solutions tailored to specific voltage, current, frequency, and phase requirements. Their products serve industries including glass manufacturing, hydrogen production, plasma arc, fibers, coatings, polysilicon, industrial heating, and heavy-duty DC rectifiers.

Product overview

Spang Power Electronics offers a comprehensive portfolio of power control and conversion solutions organized into four main product categories: SCR Power Controllers (available in both digital and analog variants), Power Systems (AC, DC, and Automation Control), Transformers (custom application), and Specialty AC & DC Drives. The digital SCR controller line includes the 1050 Series (flagship with color touchscreen and mobile apps), 1050 Nano (compact), and 850 Series, while analog controllers span the 450, 650, 750, B-Series, and C-Series lines. Power Systems provide complete packaged solutions including heavy-duty DC rectifiers for demanding applications like hydrogen generation. All products are supported by ISO 9001 certified manufacturing across their US facilities, with engineering designs exclusively US-based.
